Tech Giant: AWS ECS/ECR deployment

AWS ECS

1. create EC2 instance for docker local image creation and install docker on that.

2. create user and folders on it, assign S3FULL access and ECS role to EC2 machine

#IAM policy AmazonEC2ContainerRegistryFullAccess

#!/bin/bash

#useradd xxxx-user
#su - xxxx-user
mkdir Preventivecontrols
cd Preventivecontrols/
mkdir pc-tomcat-dinesh Preventive-control-UAT Preventive-control-DEV Preventive-control-PROD
cd pc-tomcat-dinesh/
aws s3 cp s3://man-xxxxxxxxxxxxx-user/arunk/war/local_docker_deploy_web.sh .
aws s3 cp s3://man-xxxxxxxxxxxxx-user/arunk/war/Dockerfile .

After pushing image to ECR, Now go to Task definition,

Create Task Defination

and create-Done

Now go to Cluster

create cluster - cloudprint-ec2

go to Run new Task

If get any error you can check as below:

If container running succesfully can see below:

Create Service:

(Before create service you should have load-Balancer)
but in case if something happen and task die, there is no machnisiam to comback automatically, if you say high availablity, so in order to achive this We go and create a service
